There is a few people who need to have the finger pointed at for some of 'all this mess'.
I'm not sure if I would summarize the problem exactly as you have Silverback. This
link talks about Dr Ziegler's role in dianabol being brought to the USA. I dont think the eastern bloc countries got good by simply copying what the Americans were doing in the 30's, 40's and 50's, I think they started training smarter and it was Hoffman's obsession with 'physique' over ability and simplicity that was the reason they lost out. Indeed, the eastern bloc countries had the phamaceuticals first.
When we build a time machine the hit list will include but not limited to....
Bob Hoffman for marketing his power racks and iso crap and stultifying progress in the technical aspects of OL.
Joe Weider for making people think that size and leaness was more important than strength and ability.
Arthur Jones for coming up with nautilus.
Ken Cooper for being the 'father of aerobics'.
Richard Simmons for being Richard Simmons and giving cover for all the other hucksters.
Our footballers are children of the zeitgeist these guys created and whilst Hoffman in particular was doing a lot of things then that I wish we could go back to they all are culpable to an extent with the mess things are in now.
